Reaction Steps
U.S. Pat. No. 2,088,018 describes the preparation of secondary alcohols by simple aldol condensation of aldehydes, namely 2-ethylhexaldehyde and butyraldehyde, onto ketones, namely methyl ethyl ketone, methyl amyl ketone, methyl isobutyl ketone, butylideneacetone, dipropyl ketone and methylheptanone, and the subsequent hydrogenation of the condensation products to give the saturated secondary alcohol. The aldol condensation of 2-ethylhexaldehyde onto methyl ethyl ketone and the hydrogenation of the condensation product to give 6-ethyl-3-decanol, and the subsequent sulfation thereof is described, inter alia. The use of the sulfate as surfactant is not mentioned.
